TSMC Arizona Fab Becomes a Bigger Revenue Driver as U.S. Chip Production Ramps Up
TSMC’s Arizona semiconductor facility is starting to play a more meaningful role in the company’s global business, with fresh data from Bank of America showing that the U.S. fab is contributing a growing share of the chipmaker’s revenue and profit.
The Arizona campus is one of TSMC’s most important overseas manufacturing projects and represents a major step in bringing advanced chip production to the United States. Since the project began, investors and industry watchers have closely monitored whether higher construction costs, labor expenses, and operational challenges in the U.S. would affect profitability. The latest figures suggest that the facility is moving beyond its costly buildout phase and beginning to deliver measurable financial returns.
The first phase of TSMC’s Arizona site is already operational and produces chips using the company’s 4-nanometer process technology. This is a highly advanced manufacturing node used for powerful processors, including chips tied to artificial intelligence, high-performance computing, and premium consumer electronics.
Reports have indicated that the Arizona fab is producing AI GPU-related chips for NVIDIA, while Apple is also believed to be among the facility’s early customers. These two companies are among TSMC’s most important clients, and their involvement highlights the strategic importance of the Arizona site.
However, even as wafer production expands in the U.S., some parts of the supply chain remain centered in Taiwan. TSMC’s most advanced packaging capacity is still largely based there, meaning some chips produced in Arizona may still be sent overseas for final packaging and assembly before reaching customers.
According to Bank of America’s data, TSMC’s Arizona fab first became profitable in the first quarter of 2025. Since then, its financial contribution has continued to rise. In the second quarter of 2025, the Arizona facility accounted for around 2% of TSMC’s revenue and about 1% of its profit.
The contribution has not moved in a straight line. After an initial profit decline in the third quarter, the Arizona fab’s performance improved again. Its strongest share came in the first quarter of this year, when the facility contributed more than 3% of TSMC’s profit and a similar percentage of revenue. In the following quarter, revenue contribution continued to climb, although profit share slipped below 3%.
In absolute terms, the Arizona site reached its highest revenue level in the second quarter, surpassing NT$40 billion. Profit for the same period came in below NT$19 billion. By comparison, TSMC’s total second-quarter revenue reached NT$1.2 trillion, representing annual growth of 36%.
The numbers show that while Arizona remains a relatively small part of TSMC’s global operations, its importance is increasing. A contribution of more than 4% of group sales is notable for a facility that is still in the early stages of its long-term expansion plan.
TSMC’s Arizona campus is being developed in multiple phases. The first phase focuses on 4nm production, while the second phase is expected to manufacture chips using 3nm process technology. The third phase is planned to support even more advanced nodes, including 2nm and 1.6nm technologies.
These future upgrades could make the Arizona site far more important over time, especially as demand for AI chips, cloud computing hardware, smartphones, and advanced processors continues to grow. TSMC has also started construction on the site’s first packaging facility, which could help reduce reliance on overseas packaging capacity and strengthen the U.S.-based semiconductor supply chain.
The expansion comes at a time when governments and technology companies are trying to reduce geographic concentration in chip manufacturing. TSMC’s Arizona investment is central to that effort, giving major U.S. customers closer access to advanced semiconductor production.
For TSMC, the key question has always been whether the Arizona project can scale efficiently while maintaining the company’s strong margins. The latest financial data suggests the facility is beginning to prove its value, even though it remains far from matching the scale of TSMC’s Taiwan operations.
As AI demand accelerates and customers such as NVIDIA and Apple continue to require cutting-edge chips, TSMC’s Arizona fab could become an increasingly important revenue engine. If the next phases come online as planned, the site may evolve from a symbolic U.S. manufacturing investment into a core part of TSMC’s global growth strategy.
